VAUDE-LIGHT.

Specification of Letters Patent.

Application filed August 20, 1912.

Patented Mar. 10, 19114. sei-iai No. 716,023.

To all echo/m. it 9121111/ concern Be it known that I, EMMANUEL J. AL- riiizuns, citizen ot Vthe United States, residing at N ew York. in the county ot New York and State o't New York, have invented certain new and usct'ul lmprovements in Vault- Lights, oi which the following is a specification.

This invention relates to vault lights, and

has :t'or its object the production of a glass body or lens, and a nietal holder therefor, both having special construction and arrangement. with respect to each other, the holder being adapted to be embedded in mcrete, and the lens being removably cured therein. By the use of this invention the removal ot a broken lens and the substitution ot' a new lens is rendered easy and convenient.

ln the. accompanying drawings setting t'orth the construction and arrangement otI this invention, Figure l represents a top plan view ot the holder. Fig. 2 is a bottom plan view ot' the lens. Fig. 3 is a` vertical section ot' the lens and holder assembled, the latter being surrounded by a portion of a cement vault covering.

The same letter ret'ers to the same part in the description and drawings.

In Fig. l is shown a metal lens holder A, which may be either square, or circular as illustrated. It. has one or more encircling ribs B and C, which are usually interrupted by spaces such as space The holder A has an upper shoulder D, and a lower lip E. 0n the inside or rim of the lip E of the holder is an annular, rounded projection or bead c forming part of the lip E. The lens or transparent glass body G, is constructed with an upper flange or shoulder H, and in its bottom, as best shown in Fig. 2, the lens has a circular groove J, and a central cylindrical cavity K. When the parts are assembled as shown in Fig. 3, a gasket F of packing material is placed in groove J and the groove then engages the projection e ot' the lip E ot' the holder.

ln Figs. l and 3, it will be observed that the holder A has a half-round, inwardly projecting vertical rib a, and that the lens G is provided with a groove g constructed to receive the rib o. This engagement takes place when the lens is introduced downwardly into the holder, and its purpose is to prevent the .lens from turning upon its axis when in the holder.

ln Figs. 2 aud il it is illustrated that the lensI has a depending portion L, which may extend partly around the lens as shown, or entirely around, and through the depending portion L is passed the locking pin M. It will he noted that the pin is passed through the portion L ol lens trom within the cavity K, and beneath the holder A.

The operation o't this invention is thought. to be readily discernible trom the drawings. The .lens is introduced from the top and removed the saine wav. '.lhe placing of the pin M in place prevents the displacement ot' the lens upwardly, and, as the pin is slightly wedge-shaped the lens and packing F and the holdel are tightly held together. By driving out the pin, the ends of which are exposed to the action o any convenient tool` the lens is easily removed.

What l claim is zl. The combination with a lens having a central Cavity, the wall ot the said cavity having an opening through it, a lens holder having a portion arranged contiguous to the lens exteriorly and above the said opening, and a pin removably inserted in the said ojiiening of the cavity ot the lens and projecting' outwardly below the said contiguous portion oi the lens holder.

Q. The combination with a lens having a central cavity. the wall ot the said cavity having an opening through it, a lens holder provided with external projecting portions and having an internal portion arranged contiguous to the exterior of the lens and above the said opening, and a pin removably inserted in the said opening in the wall of the lens and projecting outwardly below the said contiguous portion of the lens holder.

3. lhe combination with a lens holder, of a lens having a central cavity, the wall of the said cavity ot the lens extending below the lower surface ot the holder and having an opening through it, and a pin removably inserted in the said opening and projecting outwardly below the holder.

l. A vault light comprising a holder having an upper shoulder and a lower lip, and a lens having an upper shoulder engaging the said shoulder of the holder, the said lens having an annular `groove engaging the lip of the holder, the said lens having n eavity opening from the bottoni of the lens, the wall of the said cavity having an opening through it, and a pin removably placed in the said opening and projecting outwardly beyond the lens und below the holder.

5. A vault light comprising a holder having an upper shoulder and a lower lip, the said lip having a vertical projection, and a lens having en upper shoulder engaging the said shoulder of the holder, the said lens hving a lower portion arranged adjacent to the lip of the holder, the said lens having a vertical .groove engaging the said vertical projection of the holder, the Said lene lmving a cavity opening from the bottom of the lens, the wall of the Said cavity having :in opening through it, and 21 pin removably placed in the said opening and projecting outwardly beyond the lens;v and below the helder.

In testimony whereof I aix my signature in presence of two witnesses.
